Abstract：Objective To investigate th e clinical application value of the sixth generation Remote Medical Robot (Remebot). Methods The clinical data of 65 patients undergoing Remebot frameless stereotactic operation were analyzed retrospectively. The deep brain nucleus lesion was seen in 47 cases, including dystonia in 26, epilepsy in 15 and Parkinson's disease in 6. Brain biopsy was performed in 17 cases and Ommaya reservoir was implanted into the craniopharyngioma in 1. Results The surgical procedures were successful in all the cases without serious operation-related complications. Positioning operations were all completed once, the average operation time was 25 ± 5 min, and the average accuracy was 0.63 ± 0.11 mm. Seventeen cases of brain lesions were diagnosed by brain biopsy:astrocytoma in 8, lymphoma in 4, inflammatory lesions in 3 and brain metastases in 2. In 26 cases of dystonia patients, anterior limb stereotactic lesioning of the internal capsule was induced in 17 cases, and lesioning of the globus pallidus internus (GPi) in 9. Hippocampus and amygdala nucleus lesioning was performed in 15 patients with epilepsy. Lesioning of the GPi was carried out in 6 patients with Parkinson's disease. The symptoms of patient with craniopharyngioma were obviously improved after Ommaya reservoir implantation. And the surgical success rate was 93.75% (45/48). Conclusions The design of Remebot surgical robot is reasonable, the operation is practical and convenient with accurate positioning. The operation is safe and feasible, and has wide application prospect.
